Derecho is Forecast

After a night of terrible tornadoes, a derecho (a geographically long-lived couplex of damaging winds) is forecast to move from northwest of Nashville to Washington, DC and beyond. If you live in the 60% or 45% areas, please,

There is a risk of power failures. Get cash, fill car with fuel

Bring in any outdoor furniture, trampolines, etc.

Make sure at-risk friends and relatives are cared for. Perhaps bring them to your home before the winds arrive.

Small tornadoes can spin up in derechos but they are sometimes difficult to warn of. Usually, they are less intense than independent tornadoes.

Less concentrated damaging winds are forecast throughout the yellow region.

Please pay attention to local weather information throughout the day in these regions.
